UNITED STATES PATENT OFFICE.

CLAYTON BRUCE KEITH, OF ENUMOLAW, WASHINGTON, ASSIGNOR OF ONE-HALF TO CHARLES A. NEWMAN, OF ENUMOLAW, WASHINGTON.

ICEY-FASTENER.

T 0 all whom it may concern."

Be it known that I, CLAYTON BRUCE KEITH, a citizen of the United States, residing at Enumclaw, in the county of King and State of Washington, have invented new and useful Improvements in Key-Fasteners, of which the following is a specification.

My invention relates to key fasteners, and its primary object is to provide a device of this character which is simple, durable and efficient, and which can be manufactured and sold at a comparatively low cost.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawings, wherein Figure 1 is a view in front elevation, illustrating the application of my improved key fastener. Fig. 2 is a view in end elevation, and Fig. 3 is a detail plan view of the key fastener.

Referring to the drawings by reference numerals, 1 designates a door knob, 2 the knob s indle, 3 a key and 4 the ring of the key, al being of the usual form and construction and illustrated in connection with a lock 5, of which 6 is its latch and 7 its bolt.

8 designates the knob spindle engaging member which is designed to be constructed of a single strand of wire. The upper end of the member 8 is bent to provide a hook 9 adapted to engage the knob spindle 2, while the lower end thereof is bent to provide an eye 10.

11 designates a key engaging member which is designed to be constructed of a single strand of wire. One end of the member 11 is bent to provide an eye 12 adapted to interlock with the eye 10 to pivotally connect the members 8 and 11. The other or free end of the member 11 is bent to provide a hook 13 adapted to be passed through and I engage the ring 4 of the key, as fully illustrated in Fig. 2 of the drawing. The length of the knob spindle engaging member 8 is greater than the distance between the keyhole slot and the knob spindle, and is also greater in length than the key engaging member 11. In practice, the member 8 is applied by engaging the knob 9 thereof over Specification of Letters Patent.

Application filed October 28, 1905.

Patented March 2, 1909.

Serial No. 284,879.

the knob spindle, after which the hook 13 of the member is passed upwardly through the ring of the key, the hook 13 engaging the ring in a manner to prevent said member from becoming accidentally disengaged from the key. As the member 8 is greater in length than the distance between the keyhole slot and the knob spindle, the member 11 extends downwardly from the key. In view of the angular relation of the member 11 with the key, it is impossible to unlock a door when the device is in ap lied position, as any attempt to turn the icy would be prevented by the ring of the key coming in contact with the member 11, which is prevented from turning with the key by the member 8.

From the foregoing description, taken in connection with the accompanying drawing, the construction and mode of operation of the invention should be understood without a further extended description.

Changes in the form, proportions and minor details of construction may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the invention.

Having fully described and illustrated my invention, what I claim is:

As an article of manufacture, a key-fastener comprising a strand of wire bent at its upper end to form a spindle engaging hook and having its lower end bent to form an eye, said eye and said hook being disposed in a common plane, and a key-engaging member formed from a single strand of wire bent at one end to form an eye for pivotal engagement in the eye of the spindle-engaging member and bent at its other end to form a key-engaging hook, said eye and said hook of the key engaging member being disposed in a common plane and at right angles to the eye and hook of the spindle-engaging member to facilitate the engagement of the hook of the key-engaging member with the ring of a key.

In testimony whereof, I aflix my signature in presence of two witnesses.

CLAYTON BRUCE KEITH.
